If you follow that procedure everything, including users/plugins/etc. will be transferred.

After hours digging and digging and searching, the wonderful content server is up and running, even as a service. I had to manually copied over
1) The whole calibre library folder
2) A user database file
3) A custom-list-template file

The file /etc/systemd/system/calibre-server.service looks like this

[Unit]
Description=calibre content server
After=network.target

[Service]
Type=simple
User=root
Group=mylinuxgroup
ExecStart=/usr/bin/calibre/calibre-server --port 56965 --custom-list-template /srv/calibre/server-custom-list-template.json --userdb /srv/calibre/server-users.sqlite --enable-auth /mnt/Ebooks

[Install]
WantedBy=multi-user.target

It works. But the Book Details doesn't show Identifiers and the series index is Roman. The device has no monitor so I use only the command line interface. Can't see anything related to Book Details.
